]]> There is still quite some uncertainty about the corona-virus (Covid-19). Will it cause a pandemic? How deadly is it? Does it spread to other people easily? What is the length of the incubation period?

It has already killed more people than SARS did. To answer the question about the growth of the corona-virus I made a dashboard. It displays the amount of people that:

  • are confirmed to have the virus (Confirmed)
  • have recovered from it (Recovered)
  • have died because of it (Deaths)

The first tab displays the number of people for those categories over time while the second tab displays the number of people per location. In the left sidebar, the total amount of Confirmed, Recovered and Deaths is shown. However, you can also filter by Country or Region.

Looking at the Confirmed cases, there is a huge spike around February 12th. This is caused by the fact that also patients that have symptoms but are not tested positive (yet) are added to the reported cases.

Around, 22 February, there’s a little spike because of new cases found in Italy and South Korea. Let’s hope the numbers are going down to zero soon!

]]> In one of my last blog posts I talked about Periscope which is an R package to assist with creating scalable shiny applications. Originally it was shipped with the standard shinydashboard package but recently I have upgraded it (CRAN) so it uses shinydashboardPlus. This last package offers some nice features like a right sidebar and the possibility to add inputs to the header bar. These are the main changes in the release:

Right sidebar

Many shiny apps are using the shinydashboard package which offers a left sidebar and next to it the main body of the application. When adding lots of inputs the sidebar can get full, so in some cases it’s convenient to have a right sidebar as well. A right sidebar is one of the nice features of the shinydashboardPlus package.

Reset button

The periscope package comes by default with a reset button. This button resets your application to the state at startup. Since it’s not useful for all apps, you can disable it now using the resetbutton parameter in the function create_new_application().

Periscope sample applications

Sample shiny application demonstrating the functionality of the periscope framework. This is very useful if you are starting with the periscope package and want to explore the functionality. The screenshot below is from a sample application with a right sidebar. See sample apps to view the apps live on the periscope server.
